Abstract
The invention discloses a metallized capacitor sealing wax. The metallized capacitor sealing wax has the following formula: 30%-60% of microcrystalline wax, 20%-40% of vaseline, 2%-15% of stearic acid, 5%-15% of polyethylene, 1%-5% of dithioether, and 1%-5% of bis-dodecanol ester. Compared with the prior art, the metallized capacitor sealing wax has better toughness and plasticity and temperature tolerance, and has quite small volume shrinkage at low temperatures.
Description
Technical field
The present invention relates to a kind of sealing material, particularly a kind of sealing material of metallized capacitor.
Background technology
The production of metallized capacitor and in using, usually uses sealing material and carries out embedding between medium and between medium and pole plate, to improve electrical capacity and electrical strength.Because have good electrical property, resistance toheat and age stability performance, and cheap, and embedding wax is the first-selection of current most capacitor manufacturers.
But existing sealing wax shrinks and cracking under usually there is toughness plasticity difference, low temperature, and the hole of formation easily causes the phenomenons such as ionization, so need to carry out modification to wax, reduce volumetric shrinkage, increase its toughness plasticity.
Summary of the invention
The object of this invention is to provide the metallized capacitor sealing wax that a kind of low-temperature shrink rate is little, toughness plasticity is good.
For achieving the above object, technical scheme of the present invention is: a kind of metallized capacitor sealing wax, is characterized in that, by mass percentage, described metallized capacitor sealing wax formula is as follows:
